Abstract

The invention discloses a bumper simulated collision test system and method of an automobile. The bumper does not move while the bumper simulates a moving test method, which is convenient for obtaining detection data. The collision speed of the present invention is tested by a photoelectric method, and the pulse width and pulse quantity are directly measured by hardware, so as to avoid existing errors caused by low MCU frequency or interrupt response time. The swing angle of the collision block is measured by a magnetically sensitive angle sensor, which is more accurate. The invention collects the data collected by the collection card and uploads them to the PC, and then processes the detected signals through the industrial control software, and the signal processing is rapid.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and more specifically relates to a system and a testing method for simulated collision testing of automobile bumpers. Background technique [0002] The basic guiding ideology of the car bumper simulated crash test is to add a certain amount of reverse force to the bumper suddenly at the driving speed specified by the national standard, so that the bumper is deformed or broken, and the deformation and cracking degree of the bumper are determined. Analyze whether the performance of the bumper meets the requirements. [0003] There are two main methods to realize the simulated collision: one is that the bumper moves while the simulated collision block does not move. The second is that the bumper does not move while the simulated collision block moves. [0004] The bumper moves but the simulated collision block does not move. The bumper is installed on the simulated car bracket and hits the ...
